Not calling change on widgets after content has been injected

[joshuafcole]

This can cause CM to incorrectly track cursor position until the document is changed.

I'd like to work on this, where would the code to fix this be found? I was thinking possibly in https://github.com/witheve/Eve/blob/release/src/ide.ts#L902-L946? Also, how would I go about refreshing 'the widgets'?
Is there a resource (developer documentation?) that I can look for this kind of info?
Thanks!
